It's called comedy...
It's very obviously just for a quick laugh and you shouldn't apply real world logic.
Are you a billionaire? Or are you in the majority of people who can only wish they had a billion dollars? This is not a political game, it never tried to be, it is just for fun, and honestly, if all you see when playing games is the hidden "agenda" then you shouldn't play games at all, or just keep your opinion to yourself. And even worse, if your just seeing all the other comments about how "political it is" and parroting them, maybe you should actually play the game. It is just one form of comedy amongst many.
Either you're blind as hell, or you're just making excuses for the creator because you agree with them. I'm going with the latter, because there is absolutely no way you played this game and didn't see anything political about it. It is not a hidden agenda, it is a blatant political statement. You cannot be honest and say that it isn't. Don't be stupid, and calm the hell down.
